Oil Stain Removal from Carpet

To remove carpet stains that contain oil, you'll first need to absorb the oil. Baking soda and corn starch work best, but talcum powders also can do the trick. First sprinkle the powder liberally onto the stain and leave overnight. The next day, vacuum the powder. If there's still some discoloration left behind, try blotting the stain with a mild dishwashing liquid or laundry detergent formulated to cut oil and grease. Once the stain is lifted, blot again with a clean damp sponge or cloth.
